My present invention relates to. an improve toiiportable phonographs andhas to do with the provision oflan improved form of sounddeflectoioahorn. V

' Oneof the main advantages, of my device is that, owingto itsstructure, it is of a.com

A furtheradvantage is .the provision of means whe'reby thesounddeflectorh may be.

adjusted to varying positions soas to direct and concentrate the soundas desired. V 7 These and other capabilities will be understood as thedescription proceedsahd it is obvious that modifications may be made'inthe structure herein without departing from the spirit hereof, or thescopeof the appended Fig. 2'isa fragmentary plan view thereof 1 With thelcover :removedto better show the application of the, deflector.

swivelled tone arm 7 leading to a tortuous,

The tone chamber 8 is preferably mounted upon the under side of aplatform 6, so that in the usual style of structure the turntable thedeflector shown, in adj ustand its attached parts may be readily removedI At the center of the disks 1 O 10.is provided a pair of pivots 13-13upon which is plvotally mounted a semi-cylindrical deflector hood 14:,this beingprovided at its ends with alpair of end closure plates 1515,wherebysaid hood may be pivotally attached tothe end closing disks 1010and adjustably regulated for tone direction, as indi cated in Fig. 5,wherein theflxed deflector 9 and the pivotal hood 14 are shownconforinably assembled for radialrelative adjustment. Between) thedeflector and hood is lo- "cated a piece of felt 16, preferably afliXedto the deflector to prevent vibrationof the component metallic deflectorhood. and v to pro- Vide also a'fr-ictional means to hold the hood indesired manually adjusted'position. This figure also discloses, indotted contour, different positions of adjustment of the hood for tonedeflection.- The hood may be flared at its upper edge as at-l7, asdesired. V The. hood and deflector are so mounted as to encompass theelongated sound openmg 18 oftheinterior tapering tone chamber l .Bat itspoint ofintersection of the platform 'Y6',and the reafend ofthe, tonearm7, and thus to directthesound from the tone chamberupwardly and awayfromfthe rear offthe phoiiograph, as illustrated .by the arrows,

The foregoing detailed description has been given for clearn-ess ofunderstanding. Hence, no unnecessary limitations should be understood.Further, the appended claims should be construed as broadly aspermissible in view of the prior art, since many and various changes maybe made without departing from the scope of the invention as defined inthe broader claims.

What I claim and desire to secure by Letters Patent is:

1. In a device of the class described, a portable casing, a platform ina portion thereof, said casing having a cover, sound reproducing meansassociated with said platform one one side thereof, a tone chamberassociated with the platform on the opposite side and cooperating withsaid reproducing means to amplify sound therefrom, said platform beingprovided with an aperture communicating with said tone chamber, a tonedeflector on said platform adjacent said aperture, and a deflector hoodmovably associated with said tone deflector, said cover cooperating withsaid deflector hood, when in opened position, to direct and concentratesound issuing from said aperture.

2. In a device of the class described, a portable casing having a hingedcover, a platform in said casing adapted to support thereon soundreproducing means, said cover in closed position completely enclosingsaid means, means providing a sound amplifying chamber associated withthe under side of said platform and connected to said sound tonedeflector affixed to said platform and encompassing said aperture, adeflector hood pivotably mounted on said tone deflector, said hoodhaving a flared portion, said platform having a second aperture thereinto receive another portion of said hood when said hood is pivoted.

3. In a portable phonograph a platform, to support on the face thereof asound reproducing mechanism, an amplifying chamber, connected to saidmechanism and positioned under said platform, said chamber having asound outlet through said platform, an adjustable cylindrical sounddeflector, passing through a slot in said platform andextending oversaid outlet.

4. In a portable phonograph, a platform adapted to support on one facethereof sound reproducing mechanism, an amplifying chamber means on theother face of said platform, one end of said chamber being connected .tosaid mechanism, the other end opening into an aperture in said platform,a sound deflector surrounding said platform aperture, means associatedwith said deflector to retain the same in predetermined positions.

5. A phonograph comprising, a casing having a pivotable cover, aplatform positioned at the top of said casing and adapted to supportthereon sound reproducing mechanism,

' an amplifying tube in the space between said casing and platform, saidtube having two open ends and being tapered from one end to the other,one of said ends being connected to said mechanism, the other endregistering with an aperture in the platform, said platform havingtherein a second aperture between said first aperture and a casing wall,a pair of plates affixed to said platform, a semi-cylindrical tonedeflector affixed to said plates and platform and encompassing saidfirst aperture, a pivot plate movably mounted on each fixed plate, asemi-cylindrical deflector hood affixed at the ends thereof to saidpivot plates for movement therewith, one side of said hood being flared,the opposite side passing through a slot in said platform when said hoodis moved into non-deflecting position, apiece of felt positioned betweensaid hood and deflector to retain said hood in a predetermined position,said cover, when in open position, cooperating with said'hood, when insound deflecting position, to direct and concentrate sound issuing fromsaid first aperture.

6. A phonograph, including a platform, to support a sound reproducingmechanism thereon, a sound amplifying chamber, positioned under saidplatform, connected to said mechanism and opening into an aperture insaid platform, an adjustable cylindrical sound deflector, having thereona flared por tion, extending over said aperture and pass ing through aslot in said platform, and means for adjustably supporting saiddeflector in position.

7 A sound deflector, to be used on a portable phonograph, having thereona platform and a sound. outlet through said platform, said deflectorcomprising a semi-cylindrical hood, passing through a slot in saidplatform, adjacent said outlet, and means to pivotally position saidhood at said outlet, to extend over said outlet.

8. A sound deflector hood as in claim 7, said means including astationary cylindrical sound deflector, a portion thereof being concentrical with said hood, said hood being manually adjustable inposition with relation to said stationary deflector, and frictionalmeans on said stationary deflector, for keeping said hood in positionthereon;

9. A phonograph comprising, a casing having a cover pivoted'at the rearwall of said casing, a platform affixed to said casing di viding saidcasing into an upper and a lower compartment, when said cover is inclosed position, sound reproducing mechanism on said ment when saidcover is close platform and disposed in the dipper comdparta sounamplifying chamber in the lower compartment,

7 said chamber being connected to said mechanism, and opening into anaperture in said platform adjacent said rear wall, and a curvilinearsound deflector adjustably passing through a slot in said platform andextend-- ing over said aperture.
